| 摘 要： | 以"吉利4号"黄瓜为试材,研究高温胁迫下水杨酸对黄瓜幼苗生理特性的影响。结果表明:不同浓度的SA溶液均可降低黄瓜叶片中的相对电导率、丙二醛含量,提高黄瓜幼苗叶片中叶绿素、游离脯氨酸含量,增强根系活力;表明水杨酸能够缓解高温胁迫对黄瓜幼苗的伤害,其中以250 mg/L处理效果最好。

| Abstract: | Taking Jili 4 as experiments material;the effect of different concentrations salicylic acid on physiological character of cucumber seedlings undur high temperature stress were studied.The results showed that different concentrations of SA solution could reduce the relative conductivity and malondialdehyde(MDA) content of cucumber leaves and improve chlorophyll content of cucumber seedling leaves,free proline content,and root activity.SA could relax injury of cucumber seedling under on high temperature stres... |
